St Kitts and Nevis Weather Forecast

Detailed Meteorological Analysis and Forecast for the Period of December 21-22, 2024

This comprehensive weather forecast, valid from December 21, 2024, at an unspecified time until 8:00 AM on December 22, 2024, provides a detailed analysis of the prevailing atmospheric conditions and anticipated weather patterns for the specified period. The forecast highlights the influence of a shallow low-level system interacting with the trade wind flow, leading to a moderate chance of shower activity across the islands.

Current Weather Conditions and Temperature Trends

The prevailing weather conditions are characterized by partly sunny skies with a 40% chance of brief, passing showers. Temperatures are expected to reach a high of 31°C (88°F) and a low of 21°C (70°F), reflecting a comfortable range despite the potential for precipitation. This temperature variation is typical for tropical climates, influenced by solar radiation during the day and radiative cooling at night.

Synopsis of Atmospheric Dynamics and Precipitation Potential

The dominant meteorological feature is the presence of shallow low-level patches embedded within a moderate to fresh trade wind flow. These low-level patches create localized areas of instability, increasing the likelihood of shower development. The trade winds, originating from the east-southeast, transport moisture across the islands, contributing to the potential for precipitation. The interaction between these two atmospheric elements results in a moderate 40% chance of shower activity during the next 24 hours.

Detailed Weather Forecast for the Day and Night

The daytime forecast predicts partly sunny skies with a 40% chance of brief, passing showers. These showers are expected to be localized and of short duration, typical of convective precipitation associated with shallow low-level systems. The nighttime forecast indicates fair to partly cloudy conditions with a similarly moderate 40% chance of brief overnight showers. The cooler temperatures overnight may slightly reduce the intensity of these showers.

Analysis of Wind Patterns and Sea Conditions

The prevailing wind direction is east-southeast, with speeds ranging from 15 to 30 km/h (9 to 18 mph). The wind speeds are expected to decrease overnight, leading to lighter spells. These winds are characteristic of the trade wind regime, contributing to the overall pleasant weather conditions. Sea conditions are anticipated to be moderate, with wave heights ranging from 1.5 to 2.1 meters (5 to 7 feet). Swells are expected to reach 1.8 meters (6 feet), prompting the continuation of a high surf advisory. The combination of wind and swell conditions necessitates caution for maritime activities.

Sunrise and Sunset Times

Sunset is predicted for 5:43 PM, marking the end of daylight hours. Sunrise is anticipated for 6:36 AM the following day, signaling the start of a new day. These times are influenced by the Earth’s rotation and its position relative to the sun. The relatively short duration between sunset and sunrise is characteristic of locations closer to the equator. This detailed forecast aims to provide a comprehensive understanding of the weather conditions expected over the next 24-hour period, allowing individuals to plan their activities accordingly. The information presented encompasses various meteorological parameters, including temperature, precipitation probability, wind patterns, and sea conditions, offering a holistic view of the atmospheric state.
